To all whom it may concern:

Be it known that I, STUART W. CRAMER, a citizen of the United States, residing at Charlotte, in the county of Mecklenbur and State of North Carolina, ligve invente certain new and useful Impr vements in'Humidifiers and Air-Moistening Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

, My invention relates to means for moisteuing the air in a room or factory, has forits object to provide an apparatus which will kee the air constantly supplied with any pre erred amount of moisture and diffuse such moisture throughout the room, and the invention consists in certain improvements in construction, which will be fully dliscl0sed' in the following specification and c aims.

In the operation or practical use of. li'uniidificrs, t spray nozzle or ead in a cone like body of sufiicicnt density and velocity to draw a current of air through the casing of the humidi- I fier. The mixed air and spra assing through the casing attains consi era 10 velocity and issues radially from the casing. The atmosphere of textile factories is frequently heavily charged with lint, fl and other impurities which enter the Kumidifier with the current of air and these impurities vi orously doused with the water comprising t e spray have heretofore been collected with the surplus water and returned through the waste pipes to the water tankof the circulating system, from which the water is used over and over a ain. It is my purpose to arrest and co lectthe'se impurities and prevent them from being. re-

turned to the water tank, and also to provide ready means for cleansing the humidifier whenever found necessa The desirability ofgreater accessibility being incorporated in theconstruction of humidlfiers is shown by the .fact that attempts have already been made alon this line. This fact was recognized in my ormer patents #778,172, #792,402 and #798,880.

I wish to discriminate however, in the use of tthe vertically movable cas' as con templated at present andthat which I for mer'lyshowed the patents referred to.

Spray types of humidifiers are essentially 1e spray is delivered from the of humidifier is the one generall respectively. The up-draft, is applicable 0 only for spray reduced on an atomizer principle by both air and water; there is. not sufficient water going thro h heads where the s ray is atomized to ma e either the dri a material factor or the removal o the lint and fly collected because comparatively little of it is washed from the atmosphere. The down-draft tygpie u where hydraulic spraying is reso to for producin the spray; in this type of apparatus t e amount of water is of such consequence, that the dri must be taken care of, and that part 0 the lint and fly that collects on the inside of the apparatus must also be capable of being removed. And so, that whereas in m former patents for up-draft types of humi ifiersthe casings adjacent to the deflecting-cone, all ofwhich was; removable together,'=-therefore by con-- sidering the one of humidifier as being tlfgiother one'i'iaverwd, the removable t includedin my former'patents one of lifting downward and away the lower part from the upper part of a downd type of humidifier. y f

1 am also aware that attempts have been inilfleto facilitate cleansing in down-draft types of humidifiers by makingv separable and vertically movable the lower flared ed of the casing. That this didn'ot answer t e requirement sis evident because this conctr-action is not now used.

The troubleis the wron part was made adjustable, and as hereto ore constructed suflieient 'accessi bility-was not gained to warrant the. ad0ption of the plan profipsed. Itis believed. .however, that'by ma the lower flared portion of the casing separate and independent of the casin and by attachin said flared portion to humidi er comprisi the collecting'basin, andby supporting t e casin from either the basin itself or said upper end portion a lower part0 the cone shaped sheet of water, thereby washing it? of remo impurities" 2 a p" connected so that it may be vertically movable will do away with the undesirable features connected with constructions heretofore proposed, and render the apparatus. so

entirely accessible and so durable and workmanlike in construction as to warrant the extra expense incurred in attaining that end.

My improvements in construction facilitating inside cleaning, also provide for greater comenience in cleaning the strainer. Spray types of humidifiers are generally installed on a circulating system, whereby the surplus water is collected from eifch humidifier and returned to the storage tank, where it is partly filtered and pumped again through the supply pipes and through the heads, usually passing through a se arate small strainer attached to each humidifier. It is obvious that this is necessa nothing short of a very complete fi ering. of the water, which owing to its inconvenience and cost would be extremely undesirable, would et rid of all the impurities washed from t e atmosphere and collected in the surplus return water; the pumping of this water through the supply pipes without straining would cause the small holes of the nozzles to speedily clog u And so, small strainers attached to eac humidifier are a necessity. On the best forms of these strainers, the perforated surface is made large enough so that they can be run for quite a lon time without requiring any attention. fter a while, however, ractically all of the holes become clogg and the strainers must be removed an blown out to be cleaned. Among m ments of construction to facilita e cleaning, it is obvious that of cleaning the strainers is one of the most important. By the simple process of reversing the fiow of the water through the strainer, by the necessary plug can be blown clear in a moment and without even removing them from. their receptacles. The wash water from the strainers-canbe disposed of either directly through the'same ipe by unscrewing the nozzle or in its preerred, form it can be turned out thro h a separate opening either directl into t e waste water outlet of thehumidi er or in a down the sides and inner parts of the whole humidifier with a large flow of water under high pressure.

a ike view taken at a right angle to Fig. 7 with the casings, fan, and deflecting cone in their normal position for operation.

Reference being had to the drawin and the .designatin characters there the numeral 1', infiicates the casing of the humidifier which rests normally on the waste water receptacle or basin, and is vertically adjustable so that it can vbe raised out of the way; of the receptacle and its a purtenances to rovide read access tot ev urmdifier for t e purpose 0 cleansing it or removing adhering impurities therefrom.

2 indicates a centering and supporting spider secured to the casing and provided with a hub 3, and radial arms 4 attached to a ring 5, to theins'ide of which the casing is attached by suitable means, sudr as screws or rivets 6.

'7 is the water su ply pipe at the end of which and within t e casing 1 is a spray head 8, and the supply pipe is provided with a fitting/Z, provided with stop cocks 48 and 49. v

The casing is vertically adjustable on the supply pipe 7, and is secured in elevated posit on by-a set screw 11 in the hub 3 of' the spider.

12 indicates a stirrup, rovided with an opening .13 through whic the supply-pipe 7 passes, and proper iy centers the spray head in the casin he stirrup is secured at each end to t e supporting straps 14, 14 on which the humidifier is suspended,

artly in elevation of another type of humidifier wherein the the straps being secured to the ceiling of the room or to an overhead beam by screws 15, or other suitable means. The lower ends of the straps 14, 14 are bent to the proper an 1e and secured to the water receptacles or asinsby bolts or rivets 16.

The water receptacle comprises an up er annular basin or member, below and a jacent to the lower or discharge end of the casin and is provided with an inwardly exten ing and upwardly. projecting flan 17 set at anangle coincident with t sang e of the flaring bell-shaped terminal 18 of the casing to provide an annular air passage 19, and the flange forms a barrier to water' i deflected by the cone or deflector 29 passing. laterally out of the casing between the lowers end thereof and part 25 of said basin; The basin is also provided with an an ar or outwardly inclined flange 21 whic exthe, blowing out of the tends beyond the casing, and forms an arr-ester for accumulating 1111b, fly or other impurities which flow down: the inside oi the wall of the casing and are blown or forced out throu h the annular openin or passage 19, and dodge on the flange, i i'om which they may be readily removed when necessary. The flange 21 is provided with a series of openings 22 through which the water passes down into the lower basin, and at the perimeter of the flange is an annular upturned primarily for stiffening the flan e and at the same time prevents water am the collected lint and the like, being washed out over the extremities of the flange.

On the flange 17 are lugs 24 on which the lower end of the casingrests and by which the casing is held in proper relation to the remaining parts of the humidifier. The ln also break up or interrupt the pontiunity of the passage 19.

25 indicates the lower basin or receptacle for collecting all the waste water of the humidifier and which is permanently connected to the upper rivets 16, and between the flange 21, and the basin 25 are s )acin members 26 and which which flows form conductors for the water through the openings 22, and is discharged into the basin-25 through openings 27 in the walls of said members. The innerend of the spacing members is closed to prevent humidifier of the of water which flow heavy drops or bodies basin into the lower basin. 1

32 is a waste pipe for returning water to the supply tank, not shown, to be used over and; over again in the humidifiers.

In Fig. 6 the casing 1 edge18 is down upon and firmly aflixed to asin, butthe same result is partly accomplished by providing openings 33 circumferentially around the lower part of the flared edge 13 whereby the water collecting between the surfaces 17 and 18 can be discharged laterally outward, and where the lint and fl can settle before the water runs down t rough the o enings 22 and. out through 27 into the co let-ting the wastepipe 32.

In Figs. 7 and 8 the inner casing is designated l and the outer casing 34, both casings being supported on a spider 35, and in Fig.

7, with an extendedbracket 36 on each side working up and down in the slot 37 in the supporting straps or propelled by a motor 38', and 39 is an eye bolt in the top of the motor to engage a hook 40 for supporting the fgan in the spider with 8 is the spray head, and in this case provided with abottom inlet 41. 7 is the water supply pi e connected to the combined fitting 7', t e chamber 42 of which connects with the waste wateroutlet 32, the water inlet 43, and the strainer 44. The upperbasin is supported above the collecting asin, all as heretofore type of humidifiers. The outer casing 34 rests on an outward which in turn rests on extensions 46 of the spacing memhere 26. Referring again to Fig. 2 the strainer is designated'44. 47 is a plug for inserting and removing .the strainer when desired. 48 and 49 are plug cocks. It is obvious that the pipe 7 will pass throu h the plug cock 48 thence into the r 50 thence around and back through .the strainer 44 into the chamber 51, thence strainer through the plug cock 49 and into the spray .8. For c caning purposes it is also e plug cock 48 to cut the water out of the chamber 50 and to turn it into the chamber 51, it will from there pass in'a reverse direction through the 44 and out into the chamber'50 when the plug cock 49 in either directhe annular um- 53, from whence by turning tion the water passes into brella like shaped opening or supports with the flared hangers 14. .38 is a fan,

. this modification taking slitlltlid here 'nozzle 8 is unscrewed and the flow of water reversed for cleaning the strainer. It will be noticed that a single plug cock (l2\is subfor the two plug cocks 48 and it); also that the strainer 44 is combined with the outlet plug 47, the necessary water passages 47 being cut therein.

The fitting 7' is fixed by bolts 54 to the casing 1. In Figs. 7 and S, as already stated,

the fitting T is a combined waste water outlet and water inlet withstrainerf The opcombination, however, is exothers except that the strainer through the instead of issuing in oration of this actly the same as the wash water from the two-way plug cock 48 the conical opening 53, issues through a down discharge outlet 55 directly into chamber 42 thence into the waste pipe 32. in the nozzle 8, the modification is rendered necessary by the use of this combined fitting,

the form-of a bottom inlet 56 of the nozzle. The water is conducted upward through the arms 57 to the aperture 58, from whence it issues in the form of spra v 59 is a cleaning plug of the nozzle with an extended top 60 which fits into the hole 61 oi the supporting spider 35, thereby centering the nozzle with reference to the casing 1. While all these features above described, taken together, constitute mV improvements in the construction of humidifiers with-s ecial reference to cleanliness and immunlty from stop liness, an whereas each one of the features neally supplements the others, it is: obvious that many modifications of construction may be made without departing from the spirit of my invention.
